  • Patent number: 4641692
    Abstract: An automatic cup-filling control arrangement for beverage dispensers utilizes the spray or mist of liquid droplets, formed by flowing beverage striking beverage already in the cup, to complete an electrical circuit. This electrical circuit extends from an electrically conducting member, such as an actuating lever, to beverage flowing through a dispensing valve. When the mist of droplets permits a pre-established magnitude of current to flow between the actuating lever and the flowing beverage, which occurs when beverage in the cup reaches a pre-determined level, dispensing of the beverage is terminated.

  • Patent number: 4510376
    Abstract: This drop-down toaster has a bread support and a door at the bottom of each toasting compartment. The door has a series of vent holes for air convection which produces improved uniformity in the toast. The door and bread support are held closed by rollers on solenoid-controlled sliding bars. The rollers allow the door to swing open before the bread support is released, and they return the door and bread support to their normal condition automatically by a cam action. The bread support is cammed upwardly before release to dislodge bread from the toasting compartment guide wires. An electronic timing circuit is located in a base underneath and spaced vertically from the toasting section so that it is not affected by heat from the toasting section. The timing circuit is compensated in accordance with previous use rather than by sensing the temperature of the toasting compartment.

  • Patent number: 4267947
    Abstract: A valve arrangement for a liquid flavoring additive under pressure, particularly a non-homogeneous liquid such as high pulp orange juice concentrate, utilizes a fluid pressure to assist in terminating discharge of the liquid flavoring. The fluid pressure may be achieved by utilizing the same compressed air utilized to force the liquid flavoring through the valve structure. Suitable controls, such as a three-way valve, may be utilized to apply the pressurized air to a diaphragm on which a valve member is carried when the valve is to be closed to preclude discharge of the liquid flavoring additive, and to remove the pressure on the diaphragm, such as by venting it to air, when it is desired to permit discharge of the liquid flavoring.

  • Patent number: 4266726
    Abstract: In a beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed, provision is made for utilizing a relatively high flow rate. To achieve the relatively high flow rate, a depressurizing system utilizing a vortex chamber is located at the output end of the valve arrangement. The flow path of the diluent through the valve arrangement before the depressurizing system is designed to minimize pressure drops. Diluent leaving the depressurizing system has its velocity decreased by a diffusing structure before being passed for mixing with the syrup. The diffusing system also decreases the swirl imparted to the diluent in the depressurizing system.

  • Patent number: 4173296
    Abstract: A device for mixing and dispensing a flow of liquid concentrated beverage ingredient from a constant volume pump with a pressurized diluent supplied from a source at a preselected flow rate through a flow control device. Diluent flow and liquid concentrate flow intersect and converge into a common fluid passageway which, in turn, flows into a fluid chamber formed by a housing. A tubular spout containing first and second restrictive orifices extends into the chamber formed by the housing and is sealed thereto by a pair of seal rings. The tubular spout can be rotated to a first or second position dependent upon the consistency of the liquid concentrate desired to be dispensed, thereby selectively permitting fluid to flow through the first orifice or both orifices. The unmixed diluent and liquid concentrate in the fluid chamber flow through the orifices and are mixed therein resulting in a homogeneous and uniformly mixed beverage.

  • Patent number: 4140245
    Abstract: A recirculating carbonator and beverage dispenser requires only one pump. The system's function can be enhanced by the use of a two position spool valve having a fresh water inlet port, a carbonated water inlet port, and a fluid outlet port commonly connected with a central bore. A spool member is slidably disposed within the bore to selectively interrupt fluid communication between the carbonated water inlet port and the liquid outlet port during the presence of a low water signal generated by a level sensing device within the system's carbonation tank. During the interruption, fresh make-up water is added to the system. The level sensing device includes a body with a longitudinal bore therethrough, an inlet for the constantly flowing fluid, and a venturi tube depending from the body.
